Inmate charged with helping Minnesota murderer commit suicide

MADISON, WI-- An inmate at a Wisconsin prison has been charged with helping his cellmate, a high-profile killer from Minnesota, commit suicide in January.

Joshua Walters, an inmate at the Dodge Correctional Institution, has been charged with one felony count of assisted suicide. He is accused of helping 20-year-old Stillwater native Adam Peterson kill himself.

Peterson pleaded guilty to stabbing 31 year old Madison resident Joel Marino to death in January of 2007. He then committed suicide shortly after arriving in the state prison system.

Peterson was known to be suicidal, and was put on suicide watch while awaiting his trial. His attorney, Dennis Burke, said his client was diagnosed as psychotic and schizophrenic.
